I am look for Deer Resistant roses to plant in my garden.

So far I have a Harrison's Yellow rose and Rosa Rogusta.
The dear do not mess with these . Because they are very
thorny. What are some other Roses I can get.

Do you mean R. rugosa?

I have had deer attack "Mermaid" which has whopper thorns,
and R. sericea pteracantha ("Wingthorn"): true, both were young
plants and not producing the same large thorns that one finds on
mature specimens. I've had leaves carefully eaten off of some
pretty thorny shrub roses. The tight-spaced prickly thorns on
rugosa hybrids seem to deter deer predation a bit, and Harrison's
Yellow has Scotch rose ancestry that would arm it similarly.
I guess that anything with Scotch rose or rugosa blood might
work -- check descendants of them on helpmefind.com -- but
thorns seem to be only slight deterrent to my deer here, especially
on plants where the compound rose leaves stand well away
from thorny canes.

Good luck!
